/raw, as you're using it, is a command. I think you're looking for the event however (as in do something with the number 319 being sent to you). In this case, use:

Code:
raw 319:*: {
  ; code here
}


If you're looking for more RAW's, try /debug @d, and any server raws being sent to you will be visible (as well as those you're sending).
